Problems solved by technology

However, the aforementioned excitation light will be scattered in all directions, so it is easy to cause light leakage or mixed light, resulting in poor display quality
In addition, the current process of disposing the LEDs on the active array substrate through transposition technology is prone to misalignment, resulting in shifts of the LEDs, further affecting the accuracy of the placement of the LEDs, and exacerbating light leakage and mixed light problem

Abstract

A display panel and a manufacturing method thereof are provided. The display panel comprises an array substrate, a passivation layer disposed on the array substrate, a reflective layer disposed on thepassivation layer, and a plurality of light emitting elements disposed on the array substrate. The passivation layer has a plurality of passivation layer openings and exposes the array substrate. Thereflective layer has a plurality of first openings. The top surfaces of the light emitting elements and the top surface of the reflective layer are substantially in the same horizontal plane. A method for manufacturing the display panel is also provided.

Description

technical field [0001] The invention relates to a display panel and its manufacturing method, and in particular to a light-emitting diode display panel with a reflective layer and its manufacturing method. Background technique [0002] Light emitting diodes (LEDs) have advantages such as long life, small size, high shock resistance, low heat generation, and low power consumption, so they have been widely used as indicators or light sources in households and various devices. In recent years, light-emitting diodes have developed towards multi-color and high brightness, so their application fields have been extended to large outdoor signage, traffic lights and related fields. In the future, light-emitting diodes may even become the main lighting source with both power saving and environmental protection functions. [0003] In general, LED displays use LED grains to excite photoluminescence materials to generate fluorescence or phosphorescence excitation light. However, the af...
